quadrate, palm transversely truncated and armed below with 3 strong spines. 

 The 3 posterior pairs of pereiopoda slender and elongate, basal joint broadly 

 oval, dactylus very slender. Last pair of uropoda considerably projecting 

 beyond the preceding one, basal part much longer than the rami. Telson 

 rounded quadrangular, truncated at the tip, a little longer than it is broad. 

 Body whitish, pellucid, with yellowish intestine and dark bluish ovaries, ocular 

 pigment brownish with orange-coloured coating. Length of adult female 5 mm. 



llcHHirkx. The description and figures given by Boeck of this form 

 are rather incomplete and in some cases incorrect, probably owing to his 

 specimen being in a very bad state of preservation. It is the only, as yet, 

 known species of the genus. 



Occurrence. Boeck obtained only a single mutilated specimen of 

 this small Lysianasside at Haugesund on the west coast of Norway. I have 

 myself found it in several places, both on the south and west coast, and 

 generally in rather deep water, especially where the bottom consists of 

 coarse sand and gravel. As the limbs are rather brittle, it is not easy to 

 obtain perfect specimens by the aid of the usual dredge. 



Distribution,. British Islands. 



Gen. 3. Cheirimedon, stebbing, isss. 



Body high, compressed, with very large coxal plates. Antennae of 

 usual structure, subequal (in female). Epistome slightly projecting and defined 

 from the anterior lip by a short incision. Mandibles with the cutting edge 

 terminating exteriorly with an acute dentiform corner, palp originating at about 

 the same level as the molar expansion, less slender than in Normania, with 

 the last joint shorter, and furnished with a series of curved seta? on the inner 

 edge. First pair of maxillse with the pal]) less expanded and the basal lobe 

 somewhat larger. Lobes of 'Jnd pair of maxilla 3 shorter and broader. Maxil- 

 lipeds rather large, masticatory lobes of moderate size, basal ones normal, 

 palp well developed, with the terminal joint unguifonn. Anterior gna- 

 thopoda prehensile, terminating with a large complanated hand, succes- 

 sively expanded distally; posterior ones less slender than in Normania, 

 propodal joint oval and densely hirsute. Pereiopndn not very slender, basal 

 joint of the 3 posterior pairs very large, serrated posteriorly. Branchial la- 

 mella? of usual structure. Uropoda successively decreasing in size posteriorly, 

 last pair with the basal part rather short and thick, rami very unequal, the
